3. A large oil reservoir has a pipe diameter of 75mm and length of 2200m connected to it, as shown. Assuming laminar flow through the pipe, compute the amount of oil issuing out of the pipe as a free jet. Neglect minor losses. Use kinematic viscosity 9.20x106m?/s. and h=3m a. 2.16x103 b. 1.13x10-3 c. 3.15x10-3 d. 1.09x103

Refer to Figure 7.24. The following data were collected during the field permeability measurement of a confined aquifer using a pumping test. Determine the hydraulic conductivity of the permeable layer. Use Eq. (7.49). Thickness of the aquifer, H = 4.5 m Piezometric level and radial distance of the first observation well: h1 = 2.9 m; r1 = 17.8 m Piezometric level and radial distance of the second observation well: h2 = 1.8 m; r2 = 8.1 m Rate of discharge from pumping, q = 0.5 m3/min

A sand has Gs = 2.66. Calculate the hydraulic gradient that will cause boiling for e = 0.35, 0.45, 0.55, 0.7, and 0.8.

Bourdon-type pressure gauges are used in thousands of applications. A deadweight tester is a device that is used to calibrate pressure gauges. Investigate the operation of a deadweight pressure tester. Write a brief report to discuss your findings.
